This invention relates to means for ven tilating automobiles and more particularly to that type of ventilators generallyknown as cowl Ventilators. v

Heretofore such Ventilators have been operated, that is'to say, opened oiiclosed, either by means of a handle'projectiiig be 1m the lower edge of the automobile instrument board, or by means of a rotatable knob projecting through the instrument" board. Such means are usually placed in'su ch" a position that the driver-"of the automobile must materially change hisp'ositionto operate the same, and While in such a position which isiisua'lly awkward, the control or" the car maybe lost with i'esiilting danger to it and it's'oec iipants.

It is the'prineipaloh'j'ect of the present invention to provide a Ventilator for automobiles WhiCliWlll not necessitate any tinzite rial'change' in position ofthe driver thereof to operate thesame.

Another object is'to provide a cowl Veirtilat or for automobiles that will be" easily and quickly operable solely by the drivers foot;

Another object is'to provide novel-'meaiis for operating a cowl ventilator and for reummy holding the same in adjiisted position:

A further ohject'is to provide me"ans foro'perating a cowl ventilator"which will prevent Unauthorized opening of thesame from the eXteriorof the aiitoinohile when tlieVentilat'or is. in full closed position. v f

A still infth er 'ohfj eet,is to provide a cowl ier'itilatorior automobiles which is oper'zthle by means of pedals si'ipp'orted on th dash of the automobile, the pedals being suitably connected by linkage'sjto the yentilatoi so that upon pressure he'ing applied by the drivers foot to' one pedal or another the position of the ventilator" will be caused to be changed,

The above. being amon the 655mg of the present; invention, the same consists of certain features of construotion and combination of parts to be with reference to the aeeompafiying" drawi 1 igs' .'and then elaime'd, having the above and'other o bjets iii iew.

Figure-- 8 is a broken view taken" oii th'e in which the Ventilator is pi'yoted to the mm of the aiitomoh'ile t V Iiithje drawings the eotvl 0f the memobile is indicated as ll a'nd the dasliasflQ. Thecoi'yl 11 isprov'ided With anopening 13 in itspppeisurface, the" metal about the opening 1 8 beingbent downwardly to form the "strip 19 the ears 20 which are pivotally connected by the pins 21 to the cars 22 projectrng rearwardly from the frame 14, thereby pivotally securing the cover 17 to the cowl '11. Springs 23 surrounding the pins 21 are compressed between the ears 20 and the washers 24 held on the end of the pins 21 by the cotters 25 as clearly shown in Figure 8, thereby drawing the cars 20 and 22 in close relationship and preventing rattling oi": the parts. Secured to one 01 the ears 20, as shown, is an extending arm 26 provided at its free end with a ball 27.

Secured to the dash 12 by the bracket 28 at its upper end and the bracket 29 at its lower end is the vertical shaft 30. Rotatablv mounted on the shaft 30 between the brackets 28 and is the tubular sleeve 31 to the upper end ofwhich is non-rotatably secured the arm 32 provided at its free end with a ball Connecting theball with the ball 27 is a link composed of a tubular member 34, the opposite ends of which are identical and which are formed into sockets for receiving the balls 27 and The construction of the socket ends is clearly shown in Figures 6 and 7 and comprises two ball socket members 35 and 36, the former of which is threadably received in the ends of the tube 34 and the other of which is slidably received in the end of the tube and 1S backed up by a spring 37 normally under compression between the socket member 36 and the plug 38 and tube 34. Elongated openings 40 in the side of the tube 34 permits entrance of the balls 27 and 33 therethrough and permits them to be positioned between the socket members 35 and 36, belng held in that position between the curved end .faces of the socket members by the pressure of the springs 37.

Non-rotatably secured to the lower end of the tube 31 in such a position as to-be read-. ily accessible to the foot oi? the driver is the pedal member 41. which is provided with two divergent pedals 42 and 43 which are adapted to be engaged by the tool; of the driver and thereby cause rotation ot' the tube 3] in the desired direction.

The lower face oi the member 41 is provided with a series of notches 44 which are adapted to be engaged by the vertically movable spring pressed plunger 45 confined in the bracket 29 and which is backed by a coil spring 46. The spring pressed plunger 45 engages the notches 44 and thereby resiliently holds the member 41 in adjusted position.

It will be evident that when the pedal 43 is moved. towards the dash 12 by the pressure of the drivers foot which will cause the plunger 45 to be depressed, the tube 31 will be rotated in a like manner, causing the arm 32 to rotate about the aXis of the tube 31 and also causing the ball 33 to approach the dash, drawing the ball 27 on the arm 26 of the ventilator after it and causing the ventilator to open. lVhen pressure of the drivers foot is applied to the pedal 42 a reversal of the above movements will take place and the ventilator will be caused to close.

It is preferable to so construct the dilierent parts that when the cover 17 drops down into contact with the rub r strip 15 the spring pressed plunger 45 will be so positioned in respect to one of the notches 44 that'it will tend to cause further rotation of the member 41 in order to fully engage the notch 44. This will tend to further compress the springs 37 in the tube 34 and will cause the cover 17 to be drawn down tightly upon the rubber strip 15, there-by preventing entrance of water through the meeting surfaces and will eltectually prevent vibration and rattling of the different parts of the mechanism. 7

Another preferable feature is to so con struct the mechanism that upon pressing the pedal 42 as fully forward as possible, the ball 33 will pass across the line passing between the ball 27 and the axis of the tube 31, as is clearly shown in dotted lines in Figure 5, and will come up against some form of stop, such as the dash 12, which will hold it justover the line mentioned and not far enough to relieve the spring pressure described above which securely holds the cover 17 down on the rubber strip 15. The advantage of this feature is that any effort to open the cover 17 by raising the free edge thereof causes the linkages to assume their closed position more fully and'eiiectually prevents the raising of the cover 17. This is particularly important in automobiles of the closed type where the locking of the doors is relied upon as a theft prevention means and in which the doors could be opened by an instrument inserted through the Ventilator opening.

Formal changes may be made in the specitic embodiment of the invention described without departing from the spirit or sub stance of the broad invention, the scope of which is conilmensurate with the appended claims.
